Unknown Swiss watch brand

Hello everyone,

Today I purchase a black dial military style vintage watch on a local fly market. I think that the piece is stunning and just cost me about US$40.
The brand of the watch I never see it neither on the internet or in the wild. In fact I can't make the name of the brand from the dial. Here I attach some pictures.



My best guess is the dial is branded "Lärkan-Fuverein". At the bottom, below the mark for 30 sec it says "swiss made" with no "T" on the sides. It can't be seen from the pictures, so please you have to just believe me. When I google "Lärkan-Fuverein" nothing relevant result from the search.

The movement look fine, but without branding or serial number.I look under the balance wheel and everywhere with a magnifier glass, but I couldn't find any mark. It seems that work fine, although it too soon to tell. Here are some pictures.



Last picture it's a little blurry, I apologize for that.

The inside of the back have a what I think is a serial number and a "Swiss" inscription.



I really like this watch. I notice that the second hand is very rusty (I plan to replace it). Additionally the lume for the hand is very bright although do no last very long. The numbers do not shine at all, but its looks like it have some sort of compound on them..



I really like this watch and I plan to keep it. I just want to know a little more about it.
Any one have any reference or experience for this watch or brand?
Any information it is very much appreciated.
Thank you in advance.

I believe it may be Suverein which may translate to sovereign in one of the Nordic languages

Sarkan Suverein.
Sarkan is a city in Iran, or a man's first name.
Suverein is either 'sovereign' or a surname.
Possibly a special order watch for someone with that name.

Thanks everyone for reply.

I think that Canuck hit the nail right in the middle. More likely that the watch is either a special order for someone, as bobbee point it out, due the lack of branding in the movement and for the obscurity of the name on the dial it may be a especial order or it is a special brand from some wholesaler.

The movement is behaving very good so far, it feels smooth when winding and changing hour. Also keeps time in the order of +10 sec a day so far.

Thanks again guys, all your input it's greately appreciated.
